AnJUs'rABtn STAND;

Application filed March 31, 1924. Serial No. 703,205.

To all whom it may concern:

Be it known that I. JOHN B. MAzooH, a citizen of the United States,residing at lVeimar, in the county of Colorado and State of Texas, haveinvented certain new and useful Improvements in Adjustable Stands: and Ido declare the following to be a full, clear, andexact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in adjustable stands fortypewriters, adding machines,invalid tables, and the like, and theprincipalobject is to provide an exceptionally simple and inexpensivestand structure which may be easily assembled and may bequickly'adjusted, with ease, to any desired height.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Figure 1 is a side elevation partly in section.

Figure 2 is a central vertical sectional View, parts also of the legsbeing broken away and in section.

Figures 3 and 4 are horizontal sectional views as indicated by lines 3-3and 44 of Figs. 1 and 2, respectively.

In the drawing above brieflv described. the numerals 1 and 2 designate uer and lower leg sections telescopically engaged with each other, all ofsaid sections being preferably formed of piping. The upper sections 1may well consist of upper and lower halves 3 and 4 connected byT-couplings 5 whose lateral branches 6 extend inwardly. I have shownshort radial arms, preferably formed of piping, threaded into thebranches 6, said arms being designated by the numerals 7. At their innerends, these arms are threaded into or otherwise secured to a centralblock 8 which may well be of the cross shape shown in Fig. 4:.

At suitable points, preferabl near their lower ends, the lower legsections 2 are formed with openings 9 in their inner sides, and fromthese openings. a plurality of brace rods 10 converge upwardly andinwardly, the lower ends of these rods being bent outwardly at 11through the openings 9 and then bent downwardly at 12 within the legsections 2 and in contact with the inner sur faces of the latter. Theupper ends of the rods 10 are secured to a lower, center block I g1,527,895 v PATENT oFFlcE.

13, for instance by threading them at 14: in

suitable openings formed vertically through said block.

A central vertical screw 15 passes through central openings 16 in theupper and lower blocks 8 and 13 and has opposed threaded engagement withsaid blocks as shown, this screw being provided with a readilyaccessible hand wheel 17 by means of which it may be quickly and easilyrotated toraise or lower the upper block 8 and the leg sections 1connected therewith. The table top or other member to besupported. whichmember is designated at 18 in the drawing. may be secured to the upperends of these leg sections 1 by any suitable means. such as the flangedsockets 19.

The brace rodslO are given the formation shown before they are engagedwith the block 13 and the leg sections 2. Then, after latter are angledto permit the lower ends of the brace rods to be passed through theopenings 9. Then, theleg sections 2 are righted and the upper sections1, are telescoped therewith, the screw 15 being in the meantime, engagedwith the upper and lower blocks 8 and 13. By providing a construc tion.assembled in this manner. it'may be easily and inexpensivelymanufactured but when assembled will be rigid to the necessary degree.At any time. the height of the stand may be varied, simply by turningthe hand-wheel 17. I

As excellent results are obtainable from the details disclosed, they arepreferably followed, but within the scope of the invention as claimed,numerous minor changes may be made. 7

I claim:

1. A vertically adjustable stand comprising upper and lower leg sectionstelescoped with each other, upper and lower vertically alined centerblocks between said upper and lower leg sections respectivel radial armsextending between said upper block and said upper leg sections andrigidly secured to both, upwardly and inwardly converging bracesextending from the lower leg sections to the lower block and connectedwith both, and a central vertical screw operatively associated with bothof said blocks for raising and lowering the upper block and the upperleg sections,

2 A structure as specified in claim 1; the

lower leg sections being tubular and having 5 openings in their inner;sides, the lower ends;

of said braces being formed with horizontal portions passing outwardlythrough said openings and with vertically projecting portions at theends of said horizontal portions and received in said tubular lowersections. 10

In testimony whereof I have hereunto atfixed my signature.

JOHN B. MAZOCH
